TEMPORARY BINDER.

Application filed September 12, 1921.` Serial No. 500,043.

This invention relates to the class of te1n' porary binders in which the cover, or covers, and the contained sheets are secured together by means of a co-rd or other flexible element. The object of the invention is to provide -in such a binder simple and convenient means for securing t-he cord or cords in place after4 they have been drawn taut; and to make the securing devices of minimum thickness in order that it shall be practicable to dispose them inside the binder rather than upon the exterior thereof.

In the accompanying drawings, Figures 1 and 2 are perspective views of the binder showing the manner in which the cord is arranged. Fig. 3 is a sectional view taken in the plane of dotted line 3-3 of Fig. 4. Fig. 4 is a section on line 4-4 of Fig. 3. Fig. 5 is an enlarged fragmentary view taken in the pla-ne of line 5 5 of Fig. 4. Fig. 6 is a perspective view of one set of the securing devices.

The embodiment herein shown of the invention comprises two covers 1 connected by a. flexible back 2. Two binding strips 3 and 4 are attached to the inner side of the back 2. The binding strips 3 and 4 and the yleaves intended to be held in the binder are suitably perforated for the passage therethrough of a. cord 5. In this instance there lare two holes 6 near the middle of the binding strip 4, through which holes the middle portion of the cord 5 extends. Near the ends of the binding strip 4 are holes defined by eyelets 7 through which the cord 5 passes. The leaves are provided with circular perforations 8 (Fig. 5) which register with the eyelets 7.

The binding strip 3 is provided with openings that register with the perforations 8. Preferably the openings in the binding strip 3 are reinforced by means of eyelets 9. Attached to the binding strip 3 is an element adapted to enter the eyelet 9 and bind or clamp the cord 5 therein. In the present construction, I provide a base 10 having a perforationl through which the eyelet 9 ex! tends, said eyelet serving to secure the base 10 firmly to the binding strip 3. A cap 11 is pivoted to the base 10 at 12. On the inner or lower side of the cap 11 is a stud 13 adapted to enter the eyelet 9 and clamp the cord 5 between itself and said eyelet, as shown in Fig. 5. Preferably the cap 11 is larger than the base 10, the edges of the cap 11 being bent downwardly so as to enclose the base. The caps 11 are hinged at the outer side of the bases 10 (having reference to the ends of the binding strip), said caps, therefore, swing-v ing toward each other as they move into closed position. Those portions of the caps which extend toward the center of the binding strip are bent to form a recess 14, (Fig. 6). in which the cord 5 may lie.

It will be seen that after the cord 5 has been passed through the leaves andthrough the eyelets 9, one end of the cord may be pulled to draw the bindingv strips 3 and 4 and the leaves together at that end of the binder, whereupon the adjacent cap 11 may be swung down to clamp the cord between the stud 13 and the eyelet 9. Traction may then be exerted upon the other end of the cord to draw the cord taut, after which the other cap 11 may be swung down to clamp the cord. i

In opening the binder thecaps may be raised by gripping them with the fingernail in the recesses 14 or, more easily still, by pulling upwardlyon the free ends of the cord against the caps to cause them to open. This can be done with'one hand by holding the free ends of the cord together and pulling them. The manner in which the leverage is applied to open the caps in this way seems obvious in Fig. 5.

Since the fastening devices 9 and 11 are comparatively thin and flat, it is practicable to employ them inside the binder, as shown. as they cause no objectionable bulging, or space between the leaves and the cover.

The perforations in the leaves' are simply round holes which maybe readily punched with tools in common use.

I would have it understood that the elements herein disclosed may be employed in various arrangements without departing from the scope of the invention as set forth in the appended claims.

I claim as my invention:

1. A temporary binder having, in combination, two covers, two binding strips suit ably related to said covers, one of said strips having openings, a lcord extending through said openings. the other strip having eyelets registering with said openings, caps movably attached by the eyelets to the last mentioned binding strip and swingable on a horizontal axis alongside the eyelets over the same, and a stud on each cap adapted to enter the eyelet vand clamp the cord therein. i

2. The combination in a temporary binder, of a pair of covers arranged for extension from one another to receive fillers of different thicknesses, .one of said covers having an opening7 a cord extended therethrough to hold the covers together, any portion of the length of said cord being extended through said opening depending upon the size of filler between the covers, and a clamping member having a portion arranged to be pressed into said opening to clamp vthe portion of the cord extendingtherethrough, said member being Jformed to permit the undoing thereof simply `by pulling upon the cord.

3. In a temporary7 binder. a binding element having an opening therethrough. a base on said element` an eyelet located in said opening and serving to secure the base to the binding element, a. cap hinged `to the base, and a stud on the cap adapted to'enter the eyclet.

4f. In a temporary binder` a binding clement having` an eyelet, a cord 'passing through the eyelet, a cap pivoted to the binding element. and astud on said cap adapted to enter the eyelet and clamp the cord therein, said capsubstantially enclosing the eyelet and having a recess to accommodate the cord.

5. In a temporary binder. a binding element having an eyelet. a cord passing through the eyelet, a part pivoted with respect to the binding element and held rigidly thereon by said eyelet, and-a stud on said part adapted to enterthe eyelet and clamp the cord therein.

6. In a temporary binder. a binding element having an eyelet, a cord passing through the eyelet and arranged to lie against the face of the binding element, and a part having a projection for holding the. cord inthe eyelet and having a recess terminating in slightly spaced relation to theprojection to receive a portion of the length of thecord beneath the part when the same is in holding position.

7. In a temporary binder, a binding element having a pair of spaced eyelets, acord having free ends passing through said eyelets and arranged to extendtoward each other lying against the tace of the binding element, and lever-like members pivoted` alongside the eyelets to swing toward each other over the eyelets', said members having projections thereon for clamping the cord in the eyelets and having' portions adjacent the projections to overlie portions of the length ot' the cord ivhen the members are in holding position.

S. In a tempo 'ary binder, a binding element having an eyelet, a cord passing through the eyelet, a lever-like cap for the eyeletpivotally mounted adjacent the same to swing over the same, said cap having a stud projecting therefrom to be received in the eyelet, the stud having an enlarged rounded end arranged upon pressure being applied t0 the cap to clamp the cord between it and the side ot' the eyelet to hold the cord.

9. In a temporary binder, the combination of two covers, one having free cord ends extemling therefrom in spaced relation and the other having spaced eyelets to receive the cords, and lever-like clamping elements on the last mentioned cover pivotally attached thereto to swing over the eyelets toward each other to clamp the tree cord ends in the eyeletsv` the said cord ends being arranged to extend toward each other lying against the farce ot the cover and said clamping elements being arranged upon a pull on the cord ends to swing to an open position tree of the cord ends.

10. The combination in a temporary binder ot a pair ot' covers arranged for relative adjustment to include fillers ol varying thicknesses, the one of said covers having a fiexible cord extending therefrom and the other ot said covers having an eyelet, 'through which the cord is arranged to pass, and a c amping member swingably attached to the last mentioned cover alongside the eyelet arranged to clamp-the -cord in the eyelet. said clamping member being conformed and arranged to clamp the cord in such a ivay that it may be opened by a. pull upon the cord.

ll. In a temporary binder, a cover having an opening, a flexible cord to extend through said opening, an eyelet for said opening, and means tor clamping the cord in said eyelet comprising a base held by the eyelet flat upon the cover, a cap having a pivoting portion held between the base and cover` and means on the cap adapted to engage the cord to clamp the same in the opening.

In testimony whereof, I have hereunto set my hand.

LOUIS STEIN.
